:This invention relatesf to', a' v'devicejior cooling' and ventilating'the 4interiors Iof closedbodytypes of motor.vehicles. .1'

An'object of the'invention is to provide a device which coolsvthe interior-cia motor vehicleV byai;` cooled by ice or a capillary water soaked absorbent pad.

Another object of the invention is to provide a device that is simple in construction, durable in use, efficient in operationand can be inexpensively manufactured, for'they'purpose designed. .With theabove and other objects and'advantagesin view, the inve'ntion'cosists of .thefnovel details offconstru'ction', arrangement and' coni'- bination of partsv more fully hereinafter described, claimed and illustrated Yin lthey accompanying drawingsinrwhichi '.5 tt-,'- Figure-1 is a sectional vie.'...o a motor vehicle in whichlan embodiment'of Sth ,inventionfshown indottediinesisistud;

Figure 2 is a plan view looking downward on the cooler and distributing units with the connecting air` ducts being partly in section and partly broken away, showing the device per se, with the motor vehicle and parts thereof omitted;

Figure 3 is a longitudinal sectional view of the motor vehicle and cooling means of the device;

Figure 4 is an elevational view partly in section of a rear viewof the cooling means and Figure 5 is a sectional view on the line 5-5 of Figure 4.

Referring more in detail to the drawings, the reference numeral III designates a motor vehicle of the closed body type which is provided with the conventional luggage space II at the rear end thereof.

Built into the front of the top I2 of the vehicle is an outwardly iiared vent opening I3, the open end of which is provided with a screen I4 to prevent bugs and debris from entering the opening.

Communicating with the vent opening and built into the roof I2 are the air ducts I5 and I6 respectively which extend from opposite sides of the vent opening I3 and, following the contour of the outer edge of the roof, merge into a single duct I1 at the rear of the vehicle. In line with the vent I3 rearwardly of the screen I4 there is found a bafe I8 having concaved faces I9 and respectively, which curve in opposite directions to each other and the bafIle tends to direct the air entering the vent into both ducts I5 and I6 respectively.

'I'he duct I1 is formed integral with the upper wall of the housingMZl of a cooling unit provided w'ith aidwr chamber 2'2 and havingmeRivalsv 23'1 The housing 2| is mounted in the luggagespace I I'of thevvehicla and the yduct I1 extendsthrou'gh the upper wauzn ofthe luggage space- .Y

. The housing 2| is provided with vertical parti-A tions2`25 which form j`a centralV air chamber 26, and "outer ice' chambers",A 21' in which icel 28 jis placed bylmeans ofA hinged doors 29.`Y Chamber 26'is also provided with a hinged ldoor 30 to place water in the, chamber 26. QChambers 26 and21 have '.tubular members 3|,1 depending therefrom in'vertical relation thereto, and secured at their lowerends to theupper wall ofthe chamber ,2.2, The members 3| open' intothe chambers l26 -and 21of the housing 2|, but r the lower-ends of the members. are closed to retain water therein, which is poured into the members 3| through the open hinged `doors ofthe chambers. A, I

Air` entering the ,central chamber 2 6 leaveslthe chamber by means of. the. slots 33 formed intermediate the ports' r32 communicating with the ends of the tubes 3|, and the air drawn from the space around the tubes enters the chamber 22 through a connection 22a which opens into the chamber at a point above the water level and below an absorbent pad 35. The ice in the outer chambers will melt and ll the members 3| if they are empty, but if they are already filled, the water caused by the melting of the ice will be discharged onto the ground by means of drainage pipes 34, one for each chamber.

Air entering the housing 22 strikes the absorbent pad 35 which is supported in the housing above the water 36 by the inturned flange 31, and the passage of air through the pad which is moistened by capillary action, cools the air, and the air thus cooled passes out of the chamber 22 to the circular housing 38 by means of air ducts 39, which extend under the iioor of the lvehicle body, there being one duct on each side of each housing. Water is placed in housing 2| by means of the ller opening 48, access to which is obtained by moving the rear seat 4I of the vehicle.

The housing 38 has forwardly directed air ducts 42 for cooling the front of the body, and rearwardly directed air ducts 43 for cooling the rear of the body.

Secured to the housing 2| is the fan housing 44, having the bearing housing 45 for mounting the bearing 46, in which the drive shaft 41 of the motor 48 is mounted. The bearing housing 45 has a ange 49 to which the base 50 of the motor 48 is secured by suitable fastening means 5I, and

the motor is provided with suitable exterior leads 5| for connection to the electrical circuit of the motor vehicle. Y

The fan 52 is mounted on the forward end of the drive shaft 41 and forces the air leaving the chamber 26 to enter the housing 2'2Y to be cooled as previously described. The ice tends to cool the water in the members 3| which will cool the air passing over the members,rin addition to the cooling of the air inithehousing 22.

There'has thusA been provided, a device which will accomplish the objectsof the invention, and it is believed that the operation and construction of the invention will be apparent to those' skilled in the art. e

It is also to be understood that changes inthe minor details of construction, arrangement and' combination of parts may bevresorted to, pro- VVvided theyY fall within the spirit of the 'inven-` tion, and thescope of the appended claim. Y

Having thus described theV invention, what is` claimed as newrand desired to be secured by LettersPatent is: Y
